Thanks to AdPulp, I found out this article on Reuters which should really make us think:

“Proponents of the latest Web trends were warned on Tuesday that the rest of the world may not have a clue what they are talking about. A survey of British taxi drivers, pub landlords and hairdressers — often seen as barometers of popular trends — found that nearly 90 percent had no idea what a podcast is and more than 70 percent had never heard of blogging.”

A research by DDB London found out that there is no buzz about blogging and podcasting outside of our media industry bubble, and also that people have no understanding of what the words mean.
